Study design and mark-recapture estimates of dispersal: A case study with the endangered damselfly Coenagrion mercuriale [PDF]

open access: yes, 2012
Accurate data on dispersal ability are vital to the understanding of how species are affected by fragmented landscapes. However, three factors may limit the ability of field studies to detect a representative sample of dispersal events: (1) the number of

When Similar Individuals Don't Attract: Absence of Assortative Mating by Coloration in a Damselfly With Honest Signaling

open access: yesEthology, EarlyView.
In Acanthagrion lancea damselflies, both sexes display blue ornamentation, but do they choose mates based on it? We tested whether mutual mate choice and time constraints influence ornament evolution. Blue coloration correlated with individual quality, but individuals did not choose mates based on color, and this was unaffected by time constraints over

Immune function and parasite resistance in male and polymorphic female Coenagrion puella [PDF]

open access: yes, 2006
Background: Colour polymorphisms are widespread and one of the prime examples is the colour polymorphism in female coenagrionid damselflies: one female morph resembles the male colour (andromorph) while one, or more, female morphs are described as ...

Water availability and land‐use shape the diversity of Odonata in the Middle East

open access: yesInsect Conservation and Diversity, EarlyView.
Odonata diversity in the Middle East depends on the availability of long‐lasting waters, emphasizing the importance of preserving stable aquatic habitats for biodiversity conservation under climate change‐driven droughts. Agricultural expansion is associated with increased Odonata species richness, but overall trait diversity remains limited ...

Integrating eDNA and community science to monitor urban Odonata diversity

open access: yesInsect Conservation and Diversity, Volume 19, Issue 1, Page 84-92, January 2026.
Environmental DNA captured rare and underrepresented taxa often missed by community science observations. Community science revealed adult‐stage observations across a broader temporal window. Integrating both methods improved detection across life stages, seasons, and species prevalence.

Diversification and evolution of Hawaiian Megalagrion damselflies (Pinapinao, Odonata: Coenagrionidae) Ka Ho‘omāhuahua a me ke Kumu Ho‘omohala o nā Pinapinao Megalagrion o Hawai‘i (Odonata: Coenagrionidae)

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
The ancestor of today's pinapinao, Hawaiian Megalagrion damselflies, diverged from Ischnurinae around 51 MA and likely evolved for over 20 MA before colonizing the Northwestern Hawaiian Islands. An ancestor of Megalagrion colonized the Northwestern Hawaiian Islands and diversified into ecological niches with four new breeding habitats and two new gill ...
